Depending on the style of bow that your using, your 28" draw gives you lot's of options. I personally like my 60" Super Shrew with my 29" draw. It's a forward handle reflex deflex design and is very accurate and handy. For years before that I used r/d longbows such as JD Berry and Robertsons in the 62-66" length and those shot very well, but were not as handy as the Super Shrew. I've also used my 68" Howard Hill deflex only longbow and taken deer and bear with that. I would not go any shorter than that for my personal draw length in that style of bow.
Fred Bear used a 60 inch recurve for his personal bow, even though his company built shorter and longer bows. I think a recurve in that length is very handy and forgiving at 28-29 inch draws (I'm shooting a 60 inch 1971 Super Kodiak that's a joy to shoot at my 29" draw).
I can't personally say that I notice a difference between the shorter and longer bows with my accuracy at my hunting ranges (25 yards or less and average is probably around 15 yards). Having a shorter bow gives me a little more flexability in my stand/blind location and setup.
There's a plethora of bow choices out there today and designs are taking into account shootability and length. Consider your hunting situations and stand/blind types. Take a stick the length of your proposed bow out to some of your blind/stand locations and pretend draw without looking at the ends. Do you hit something without thinking about the bow position?? For me the most natural shot sequence is drawing my bow in a hunting situation without thinking about my can't or style while the game is right there in front of me.
Good luck with your search.
